CABLE, CHAIN, on AnaLosous nnrvn.

Application filed February 26,

T 0 all whom it may concern:

Be it known that I, ARTHUR O. DUrUY, a citizen of the United States, resident of Cleveland, county of Cuyahoga, and bltate of Ohio, have invented new and useful Improvements in Cable, Chain, or Analogous Drives, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to driving mechanism and particularly to driving means involving a pair of sheaves or sprocketwheels or analogous driving members disposed in relatively oblique positions. Particularly, my invention is designedfor use in connection with the pallet-conveying mechanism of brick making plants shown and described in my pending application for U. S. Letters Patent, Serial It is designed to so arrange and actuate a air of driving sheaves or sprocketwheels that the top strands of a pair of endless ropes or chains driven by said wheels travel a certain distance apart and the lower strands thereof travel intermediate said top strands and a less distance apart.

The annexed drawings and the following description set forth in detail certain means embodying my invention, the disclosed means, however, constituting but one of yarious mechanical forms in which the principle of the invention may be employed.

In said annexed drawings:

Figure 1 represents a partial side elevation and partial axial vertical section of my improved driving mechanism; Fig. 2 represents a front elevation thereof; Fig. 3 represents a section of a detail, taken in the plane indicated by the line Ill-J11, Fig. 4; Fig. l represents an elevation of one of the driving sheaves; Fig. 5 represents a vertical axial section, taken in the plane indicated by the line V-V, Fig. l; Fig. 6 represents a plan view of the mechanism; Fig. 7 represent a suggestion of an inside elevation of one of the driving sheaves, illustrating different positions assumed by the automatically adaptable means connecting said sheaves and the main driving member; Fig. 8 represents an elevation of one ide of the mechanism, shown for the purpose Specification of Letters Patent.

of illustrating further the adaptability shown in Fig. 7

Referring to the annexed drawings, a main driving shaft 1 is shown, the same being driven by any suitable source of power (not shown). Loosely mounted upon said shaft 1 is a pinion 2 which is adapted by a suitable clutch mechanism to be thrown into rotative engagement with said shaft and to actuate a gear 3 provided with the enlarged arm portions 3 a certain use for which-will be hereinafter fully explained. Said gear 3 is rotatably mounted upon a journal member 4 supported in a manner hereinafter fully explained. Secured to a main supporting frame 6 and upon either side thereof are a pair of brackets 5 disposed in the generally oblique relative positions plainly shown in Fig. 1. A pair of inwardly projecting members provided with journal surfaces 7 are secured in said brackets 5 by means of the screws 8 and key and key-way 9. The inner ends of said journal members 7 are supported in a pair of bevel collars 10, which collars are disposed intermediately the hub members 18 of a pair of sheaves 13, hereinafter more fully described, and the outer surfaces of the hub member of the gear 3. The inner ends 7 of said journal members 7 are beveled, as plainly indicated in Fig. 1, and

disposed between said inner surfaces 7 and supported and alined by means of keys and key-ways 11 and screws 12 in the bevel collars 10 is the journal member 4, hereinbefore mentioned, upon which the ear 3 rotates. Disposed upon the journals 5, thus obliquely supported relatively to each other, are a pair of sheaves 13 provided with the hub portions 13' and with enlarged portions 13*, Figs. 3 and fl, hereinafter more dully described, each formed with a hole 13 and a slot 13 intersecting aid hole. Alternate arms 3' of the gear 3 are provided with enlarged portions 3 as plainly shown in Fig. 1, within which portions 3 bars 1e are symmetrically secured, there being three of said bars, as is plainly indicated in Fig. 7. Connected to the outer ends of each of said bars 1d are a pair of links 15 of the general design shown plainly in Figs. 7 and 8, said links 15 being provided with enlarged holes intersected by the bars ll and retained upon said bars by intersecting pin .wheels and 17. The other ends of the links 15 intersect the slots 13 of the sheaves 13 hereinbefore mentioned and are retained therein by pins 15 disposed within the holes 13 and therein retained by the pin 16, all as plainly shown in Fig. 3, the holes of the links 15 through which said pins 15 are inserted being enlarged.

It is evident from the foregoing description that the actuation of the driving shaft 1 will rotate the gear 3 through the pinion 2, which action will rotate the bars 14 and consequently the links 15, resulting in the rotation of the pair of sheaves 13 in the oblique relation shown in Fig. 1. This action results in the driving of a pair of endless cables a certain distance apart in one direction and a lesser distance apart in the other direction and above or below the horizontal position assumed in the first-mentioned di rection. As plainly shown in Figs. 7 and 8, the enlarged holes provided in both ends of the links 15 intersected by the bars la and the connecting pins 15, respectively, provide for the ne ssary changes in the elfective lengths an relative positions of the links 15 produced during the rotation by the relative obliquity of the sheaves 13 to the gear 8.

It is apparent that the sheaves 13 may be driven by means other than the specific driving means hereinbefore described and shown in the accompanying drawings, such as bevel gears, worms, etc. Furthermore, flexible members connecting member 3 and the pair of sheaves 18 could be utilized instead of rigid automatically adaptable links as shown. Such flexible members could be chainsor ropes or other suitable members'ia It is further evident that the pair of driving wheels 13 might be chai'. sprockets or analogous driving means instead of rope sheaves.
